<h1 id="purpose">Purpose</h1>
<p>The CMSIS-RTOS v2 (CMSIS-RTOS2) provides generic RTOS interfaces for Arm® Cortex® processor-based devices. It provides a standardized API for software components that require RTOS functionality and gives therefore serious benefits to the users and the software industry:</p>
<ul>
<li>CMSIS-RTOS2 provides basic features that are required in many applications.</li>
<li>The unified feature set of the CMSIS-RTOS2 reduces learning efforts and simplifies sharing of software components.</li>
<li>Middleware components that use the CMSIS-RTOS2 are RTOS agnostic and are easier to adapt.</li>
<li>Standard project templates of the CMSIS-RTOS2 may be shipped with freely available CMSIS-RTOS2 implementations.</li>
</ul>
<p>This CMSIS-RTOS v2 represents a wrapper layer for CMSIS RTOS v2 APIs implementation based on threadX RTOS APIs.</p>
